Stable kernels 3.0.20 and 3.2.5

The 3.0.20 and 3.2.5 stable kernel updates have been released. They are single-patch updates containing the fix to the ASPM-related problem that would significantly increase power consumption on some systems. This patch has been treated with some care: it seems to work, but nobody really knows if it might cause behavioral problems on some obscure hardware. That said, at this point, it seems safe enough to have found its way into a stable update.
